| 摘 要： | 试验以雏鹅为对象,研究了不同能量水平对雏鹅卵黄囊吸收利用的影响。结果表明,在59时龄以内80%以上的卵黄囊营养被吸收利用,说明这一时期是卵黄囊吸收利用的主要时期。能量水平对卵黄囊营养的吸收与利用有一定的影响,低能日粮有加速卵黄囊吸收与利用的趋势,但各采食组之间差异不显著(P>0.05)。

| Abstract: | An experiment was conducted with gosling to study the effects of different levels of energy on absorption and utilization of yolk sac.The results showed that more than80%of nutrition in yolk sac were utilized in59hours,which suggested that it was the main period of yolk sac utilization.Energy had a little influence on the absorption and utilization of yolk,low energy had a tendency to accelerate absorbing and utilizing the yolk nutrient ,but not significantly(P>0.05).The further research should be conducted. |
